ARCH-RAISING MACHINE. i

Applicationk led January 19, 1924. Serial No. 687,241.

To all whom z't may concern:

Be it known that I, FRANK M. NAYsMrrH, a citizen of the United States, residing at Kansas City, in the countyof Jackson and State of Missouri, have invented certain new and useful Improvements in Arch-Raising Machines; and I do declare the following to be a full, clear, and exact description 'of the invention, such as will enable others tarsal bones, the machine being used at convenient intervals so that after a number of treatments, the'` articulation will be corrected and the bones of the foot will remain in their normal positions. The device is so constructed that the patient may operate it in an easy manner so that home treatment may v be provided by using my invention.

The simplicity of the structure as well as the novel manner of operating the invention will be apparent by reference to the fol-` lowing description in connection withthe accompanying drawings in which- Fig. 1 1s a perspective view of an arch raising machine constructed in accordance with my invention. v

Fig. 2 is a cross wsectional view through the bridge bar for raising the arch.

Fig. 3 is a bottom perspective view of the f machine, the operating lever being shown in fragmentary perspective and parts of the straps being broken away, and

Flg. 4 is a perspective view of the part of the base showing the pad in perspective with the bridge bar in position to raise it.

'The base 1 may consist of an elongated block with a cut-a-way portion 2 at its rear en d and grooves 3v and 4 intermediate its ends. The cut-away portion 2 receives an ankle strap 5 which is held in place yby the L-shaped cleats 6 and 7 which span the cuta-way portion to hold the strap 5 to the base as wil be clearly lseen` by reference to Fig: 3. ongitudinal bars 8 and 9 bridge the grooves 3 and 4 to hold the strap 10 in the grooves, it being observed that the strap has a double lap, that is', it passes from groove 3 around the foot in the groove 4 and then the end is fastened by a buckle connection as at 11. The edges of the base or block are in-cut far enough to receive the strap 10 so that the operating lever 12 may swing on its pivots 13 and 14 without coming into Contact with the straps.

The operating leverhas two side bars 15 and 16 connected at their upper ends by a handle- 17 which may be grasped by the operator to swing the lower edges of the lever on the pivots 13 and 14. The lever constitutes an actuator with the lower ends ot' the side bars 15 and lturned into elbows or right angular extensions 18 and 19 which may press upward on the bridge or arch bar 20 consisting of the metal bar having depending ends 21 and carrying a wooden bar 22 which contacts with a flexible pad 23 -fastened at its 'respective ends 24' and 25 to the blockand intermediate its ends to the bar 22 so that when the arch bar is raised the pad will press against the metatarsal bones and raise the arch.

Of course in order to properly raise the arch the foot must be strapped onto the base 1 by the straps a-nd 10 as shown in Fig. 1. The operator may then push forward on the upper end of the actuator or lever, 12. The outward swinging motion of the lever is variable of course, depending upon the patient being treated. If a very flat arch is to be reconstructed the initial movements of ,the lever will be comparatively slight until towards the last after the arch begins to assume its proper form, then the lever can be drawn very far forward. In all instances the lever should be drawn as far 4forward as possible without causin too much pain to the patient and held t ere for an appreciable time to allow the bones to accommo date themselves to the new position, and

ultimately the bonescan be pushed back to rest, means for s uring the foot to the rest,

a transverse arc elevating bar carried by the rest','having an upper edge portion to engage under the arch of the foot, an actuatortherefor, and a flexible pad of greater Width than the width of the bar secured end of the bar and an actuator pivoted tok the side of the foot rest and having projections engaging under the projections on the end of the bar for raising it.

3. An arch restorer device comprising a foot rest, spaced foot securing means carried by the rest, an arch elevating bar loosely 'mounted in the slot in the rest and havhr ing end projections and a lever pivoted to the side of the foot rest and having right angular projections for engaging under the projections on the foot rest.

4. An arch restoring means comprising a foot rest, straps for securing the foot to the rest, a vertically movable transversely disposed bar mounted in the foot rest, a pad over the bar, projections on the end of the bar and an elbow lever having a long arm and a short arm, the shortarm resting under one of the projections on the bar to raise it. v

5. An arch elevating means comprising a foot rest, means forsecuring the foqt to the rest, an arch eleva-ting bar transversely of the rest having projections, a eXible pad above the arch elevating bar and an elbow ever pivoted to the foot rest for raising the 6. In an arch restoring device, a foot rest having a slot, means for securing the foot to the rest, an arch elevating bar in the slot, mounted for vertical movement and a lever for raising said bar.

7. In an arch restoring device, a foot rest having a slot, means for securing the foot to the rest, an arch elevating bar in the slot, mounted for vertical movement, and a lever for raising said bar, said lever being formed at its end with an elbow to provide a toe to engage under the bar.

8. In an arch restoring device, a foot rest having a slot intermediate its ends, a transverse bar vertically slidable in said slot, an operating lever for said bar, pivoted to the foot rest, a iexible pad secured to the foot rest and bridging the bar, an ankle strap carried by the rest and a strap carried by the rest for securing the forward portion of the foot-thereto.

In-testimony whereof I aiiX my signature.
